Not only is having a dry mouth uncomfortable, but it also contributes to tooth decay and to cavities because people with dry mouth do not produce enough saliva, which has bacterial properties. Chewing xylitol gum is a convenient and unobtrusive way of addressing both of these issues. Xylitol gum simulates saliva production, which helps relieve symptoms in more minor cases of dry mouth. In addit...
The purpose was to evaluate the microbiological mechanism of action of xylitol and to assess its use in clinical practice for preventing acute otitis media (AOM). To test whether the effect of xylitol on S. pneumoniae is inhibited by fructose, a total of 20 strains of S. pneumoniae were exposed to xylitol in the presence of fructose and other carbon sources. Addition of 5% xylitol to the media ...
Rusks are mostly used at breakfast in Asian countries like India and Pakistan. Effect of replacement of xylitol on physicochemical and sensory parameters of rusks at various levels of sugar replacement from 0100% was studied. Physicochemical and sensory characteristics were studied at storage intervals of 0, 10, 20 and 30 days to find out the best treatment for mass production. The moisture con...
The most widely used sugar alcohols are: xylitol, sorbitol, mannitol, maltitol, lactitol and the products Lycasin® and Palatinit®. It is often claimed that xylitol is superior to the other sugar alcohols for caries control. This paper examines clinical studies on the caries-preventive and therapeutic effects of sugar alcohols with emphasis on sorbitol and xylitol. It is concluded that chewing s...
OBJECTIVES/HYPOTHESIS To determine the tolerability of xylitol mixed with water as a nasal irrigant and to evaluate whether xylitol nasal irrigation results in symptomatic improvement of subjects with chronic rhinosinusitis. STUDY DESIGN A prospective, randomized, double-blinded, controlled crossover pilot study. METHODS Twenty subjects were instructed to perform sequential 10-day courses o...
BACKGROUND The plant biomass and agro-industrial wastes show great potential for their use as attractive low cost substrates in biotechnological processes. Wheat straw and corn cob as hemicellulosic substrates were acid hydrolyzed and enzymatically saccharified for high xylose production. The hydrolysate was concentrated and fermented by using Saccharomyces cerevisiae and Kluyveromyces for prod...
Sweeteners are divided by their sources into natural and synthetic and by their nutritional values into nutritive and non-nutritive. Xylitol is a five carbon natural sweetener found in fibrous vegetables and fruit, which offers many health benefits to human. On oral health xylitol prevents dental caries, retards demineralization of tooth enamel, promotes remineralization of tooth enamel, increa...
Editorial Xylitol research has been conducted since the early 70's; at the beginning of 2009 there were almost 500 PubMed-indexed papers on " xylitol and dental ". Xylitol research was initiated in Finland, but nowadays the majority of papers are published by non-Finnish authors. Xylitol studies have been criticized mainly by European researchers. This criticism is reflected for example in the ...
Whole cells and a cell extract of Pachysolen tannophilus converted xylose to xylitol, ethanol, and CO(2). The whole-cell system converted xylitol slowly to CO(2) and little ethanol was produced, whereas the cell-free system converted xylitol quantitatively to ethanol (1.64 mol of ethanol per mol of xylitol) and CO(2). The supernatant solution from high-speed centrifugation (100,000 x g) of the ...
d-Arabitol was observed to be toxic to many laboratory strains of Escherichia coli K-12, and xylitol was found to be toxic to an existing E. coli C mutant strain. Fructose-specific components of the phosphoenolpyruvate:sugar phosphotransferase system are required for xylitol toxicity. Selection for xylitol resistance results in Fru(-) strains blocked in fructose phosphotransferase. Introduction...
